The atomizer 1 and the host 2 can be arranged in an integral manner or can be detachably connected, and can be designed according to specific needs.

[0051] See also Figure 2 , Figure 2 It is a structural schematic diagram of the atomizer provided in this application.

[0052] The atomizer 1 includes a shell 10, an atomizer core 13 and an atomizer seat 30. The atomizer core 13 is at least partially disposed in a receiving cavity (not shown) formed by the atomizer seat 30; specifically, the atomizer seat 30 includes a top cover 11 and a base 12, and the top cover 11 and the base 12 cooperate to form a receiving cavity. The shell 10 forms a liquid storage cavity 14 and an air outlet channel 15, and the liquid storage cavity 14 is arranged around the air outlet channel 15; the shell 10 also forms an installation cavity 16 connected to the liquid storage cavity 14, and the base 12 is arranged in the installation cavity 16; the top cover 11 is embedded in one end of the base 12 close to the air outlet channel 15, and covers the atomizer core 13, and blocks the liquid storage cavity 14 and the air outlet channel 15.

[0053] In the width direction of the atomizer 1, a lower liquid channel 17 is formed between the outer surfaces of the two opposite side walls of the base 12 and the inner surface of the mounting cavity 16; specifically, the two opposite side walls of the base 12 are concave curved surfaces to form a liquid guide groove extending along the axial direction of the atomizer 1, and a lower liquid channel 17 is formed between the liquid guide groove and the inner surface of the mounting cavity 16. The matrix to be atomized in the liquid storage cavity 14 enters the atomizing core 13 through the lower liquid channel 17, and is atomized by the atomizing core 13 to produce an aerosol. In this embodiment, the atomizing surface of the atomizing core 13 is arranged toward the air outlet channel 15, which shortens the path of the aerosol atomized by the atomizing core 13 to enter the air outlet channel 15 to the maximum extent, can avoid aerosol residue as much as possible, reduce the generation of condensate, and increase the aerosol concentration, thereby improving the user experience.

[0054] It can be understood that an atomizing chamber 18 is formed between the side of the top cover 11 close to the atomizing core 13 and the atomizing surface of the atomizing core 13, and a vent hole 111 is provided on the top cover 11, which connects the atomizing chamber 18 and the air outlet channel 15, so that the aerosol atomized by the atomizing core 13 enters the air outlet channel 15 through the vent hole 111. An inhalation hole 151 is provided at one end of the air outlet channel 15 away from the top cover 11, and the user inhales the aerosol through the inhalation hole 151 to obtain the effective substance in the aerosol; optionally, the effective substance includes nicotine and flavoring.

[0055] See also Figure 3 , Figure 3 It is a cross-sectional schematic diagram of the first embodiment of the base in the atomizer provided in the present application.

[0056] The atomizer seat 30 is provided with a ventilation structure 121 and an air guide structure (not shown), and the ventilation structure 121 connects the air guide structure with the outside atmosphere; the air guide structure guides the airflow to flow to the atomization surface in at least three directions and converges on the atomization surface, and then enters the air outlet channel 15, which reduces the generation of eddy currents on the atomization surface, further reduces aerosol residue, and further reduces the generation of condensate. Specifically, the setting method of the ventilation structure 121 and the air guide structure is designed according to needs, and it is sufficient to be able to perform its functions; the following introduces several specific settings of the ventilation structure 121 and the air guide structure.

[0057] The base 12 includes a base body 124 and a protrusion 125 disposed on the base body 124. The base body 124 is located on a side of the protrusion 125 away from the air outlet channel 15. The outer surface of the base body 124 matches the inner surface of the port of the mounting cavity 16 to block the mounting cavity 16. The outer surfaces of the two side walls of the protrusion 125 in the thickness direction of the atomizer 1 match the inner surface of the mounting cavity 16. The outer surfaces of the two side walls of the protrusion 125 in the width direction of the atomizer 1 are spaced from the inner surface of the mounting cavity 16. For example, the outer surfaces of the two side walls of the protrusion 125 in the width direction of the atomizer 1 are concave to form a liquid guide groove 126 extending along the axial direction of the atomizer 1. The base 12 has a through hole 127 passing through the base body 124 and the protrusion 125 to form a receiving cavity for installing the atomizer core 13. Therefore, the base 12 is a side wall arranged in an annular manner as a whole. In this embodiment, the atomizer core 13 is completely received in the receiving cavity.

[0058] The base 12 is provided with a ventilation structure 121 connected to the outside atmosphere. In the present embodiment, the ventilation structure 121 is a through hole extending axially on at least one side wall of the base 12. A flange 122 is provided on the inner surface of the base 12 in the circumferential direction, and a first groove 1221 is provided on the surface of the flange 122 facing the air outlet channel 15. The first groove 1221 is connected to the ventilation structure 121, and a notch 1222 is provided on the side wall of the first groove 1221, so that the gas in the ventilation structure 121 flows along the first groove 1221 and flows out from the notch 1222, and then converges on the atomization surface of the atomization core 13 and enters the air outlet channel 15. Optionally, the bottom surface of the notch 1222 is slightly higher than the atomization surface, so that the airflow converges on the atomization surface. Optionally, the bottom surface of the first groove 1221, the bottom surface of the notch 1222 and the atomization surface are coplanar, so that the airflow converges on the atomization surface. The distance between the bottom surface of the notch 1222 and the atomizing surface can be designed as required, and the airflow only needs to be converged on the atomizing surface before entering the air outlet channel 15 .

[0059] Since the top cover 11 is embedded in one end of the base 12 close to the air outlet channel 15 and covers the atomizer core 13, that is, the top cover 11 is arranged on the surface of the flange 122 facing the air outlet channel 15 and covers the first groove 1221; and only the vent hole 111 is arranged on the top cover 11, so that the outside air enters the first groove 1221 through the ventilation structure 121, and can only flow to the atomization surface of the atomizer core 13 through the notch 1222 on the side wall of the first groove 1221, and after converging on the atomization surface, it carries the aerosol into the air outlet channel 15 through the vent hole 111. That is, the first groove 1221, the notch 1222 and the top cover 11 cooperate to form an air guide structure, so that the airflow converges at the center of the atomization surface and then enters the air outlet channel 15.

[0060] By arranging a flange 122 on the base 12, arranging a first groove 1221 on the flange 122, and arranging a notch 1222 on the side wall of the first groove 1221, the gas is gathered on the atomization surface and then enters the gas outlet channel 15, which can reduce the generation of vortex in the atomization chamber 18, further avoid the residue of aerosol, reduce the generation of condensate, and increase the solubility of large particles in the aerosol, so that the aroma restoration degree and dessert will be relatively high.

[0062] Specifically, the first groove 1221 is an annular structure and is arranged along the circumference of the flange 122; a plurality of notches 1222 are symmetrically arranged on the side wall of the first groove 1221. In one embodiment, the first groove 1221 is arranged to form a rectangle; four notches 1222 are symmetrically arranged on the side wall of the first groove 1221, which are correspondingly arranged at the midpoints of the four sides of the rectangle (such as Figure 4 In another embodiment, the first groove 1221 is arranged to form a rectangle; eight notches 1222 are symmetrically arranged on the side wall of the first groove 1221, correspondingly arranged at the midpoints and four corners of the four sides of the rectangle (as shown in FIG. Figure 5 shown).

Figure 6e yes Figure 4 A simulation diagram of the airway structure is shown.

[0064] See also Figure 6a The outside atmosphere enters the first groove 1221 through the ventilation structure 121, gathers the airflow from four directions and discharges it from the central air outlet channel 15, thereby reducing the aerosol residue in the atomization chamber 18. Figure 6c , the aerosol concentration in area A is higher, and condensate accumulation is more likely to occur in area B. Figure 6d , strong eddy currents are likely to occur in area C. Figure 4 The simulation results of the airway structure shown are shown in Table 1.

[0065] Table 1 Simulation results of airway structure

[0066]

[0067] See also Figure 6e , four notches 1222 are provided on the first groove 1221, so that a strong eddy zone is generated at the corner of the atomizing chamber 18, which is not conducive to aerosol transmission and condensate is easily accumulated at the corner. By providing the first groove 1221 and the four notches 1222, an annular airway structure is formed, and airflow is gathered from all sides from four directions, so that the outside atmosphere and the atomized aerosol are better mixed.

[0068] For further information, see Figure 5 , the first groove 1221 is arranged to form a rectangle; notches 1222 are provided not only at the midpoints of the four sides of the rectangle, but also at the four corners. By also providing notches 1222 at the four corners of the rectangle, the airflow is gathered from all sides from eight directions, and then enters the air outlet channel 15 after converging at the center of the atomization surface, further solving the problem that strong eddy currents are easily generated at the corners of the atomization surface, and condensate is easily accumulated; and the aerosol residue in the atomization chamber 18 is minimized, so that the external atmosphere and the atomized aerosol are better mixed, and the aroma reduction of the effective substance in the aerosol is better.

[0069] See also Figure 7 , Figure 7 It is a cross-sectional schematic diagram of the second embodiment of the base in the atomizer provided in the present application.

[0070] In the second embodiment of the base 12, its structure is basically the same as that of the first embodiment of the base 12, except that a protrusion 128 is further provided on the inner surface of the base 12 in the circumferential direction, and the surface of the protrusion 128 close to the flange 122 covers the first groove 1221, so that the first groove 1221, the notch 1222 provided on the side wall of the first groove 1221 and the protrusion 128 cooperate to form an air guide structure, so that the airflow converges at the center of the atomization surface and then enters the air outlet channel 15. Optionally, the protrusion 128 is integrally formed with the flange 122. In the second embodiment of the base 12, the first groove 1221 and the notch 1222 are provided in the same manner as in the first embodiment of the base 12, and will not be repeated.

[0071] It can be understood that in the second embodiment of the base 12, the top cover 11 is arranged at one end of the base 12 close to the air outlet channel 15, and a vent hole 111 is provided on the top cover 11 to communicate with the air outlet channel 15. The thickness of the top cover 11 is thinner than that in the first embodiment of the base 12.

[0072] See also Figure 8 , Figure 8 It is a structural schematic diagram of another embodiment of the top cover in the atomizer core provided in the present application.

[0073] The air guide structure can also be formed at one end of the top cover 11 away from the air outlet channel 15. In one embodiment, the atomizer core 12 is completely accommodated in the accommodating cavity of the base 12; an annular groove 112 is provided on the surface of the top cover 11 away from the air outlet channel 15, and a plurality of ventilation grooves 113 are symmetrically provided on the inner side of the annular groove 112 away from the shell 10, and the ventilation grooves 113 are connected to the atomization cavity. The surface of the base 12 close to the air outlet channel 15 is arranged in abutment with the surface of the top cover 11 away from the air outlet channel 15, and covers the annular groove 112 on the top cover 11, and makes the ventilation grooves 113 connected to the atomization cavity; the ventilation structure 121 on the base 12 is connected with the annular groove 112, so that the annular groove 112, the ventilation groove 113 and the base 12 cooperate to form an air guide structure, and the airflow converges at the center of the atomization surface and then enters the air outlet channel 15 through the ventilation hole 111 of the top cover 11.

[0074] In another embodiment, a first groove 1221 may be provided on the base 12, and a plurality of notches 1222 may be symmetrically provided on the side wall of the first groove 1221; and an annular groove 112 may be provided on the surface of the top cover 11 away from the air outlet channel 15, and a plurality of ventilation grooves 113 may be symmetrically provided on the inner side surface of the annular groove 112 away from the shell 10, and the ventilation grooves 113 may be connected with the atomization chamber near the side wall of the base 12; the shape and size of the first groove 1221 and the annular groove 112 may be matched, and the shape and size of the notches 1222 and the ventilation grooves 113 may be matched, so that the first groove 1221, the annular groove 112, the notches 1222, and the ventilation grooves 113 may be matched to form an air guide structure, and the airflow may converge at the center of the atomization surface and then enter the air outlet channel 15 through the ventilation hole 111 of the top cover 11.

[0075] It is understandable that the air guide structure can be set in a variety of ways. It can be formed on the top cover 11, or on the base 12, or formed by the top cover 11 and the base 12. It only needs to enable the airflow to flow to the atomization surface in at least three directions and converge on the atomization surface before entering the air outlet channel. The specific setting method is designed according to needs. The atomization core 13 can be completely accommodated in the accommodation cavity formed by the base 12; it can also be partially accommodated in the accommodation cavity formed by the base 12 and partially accommodated in the cavity formed by the top cover 11. Other structures are changed accordingly to enable the airflow to flow to the atomization surface in at least three directions and converge on the atomization surface before entering the air outlet channel.

[0076] See also Fig. 9 and Fig.10 , Fig. 9 is a schematic diagram of the structure of the atomizer core in the atomizer provided in this application, Fig.10 It is a cross-sectional schematic diagram of the atomizer core in the atomizer provided in the present application.

[0077] The atomizing core 13 includes a heating element 131 and a liquid guide element 132, and the heating element 131 is arranged on the side of the liquid guide element 132 close to the air outlet channel 15. The liquid guide element 132 includes a porous ceramic element 1321 and a porous cotton rope element 1322; at least part of the porous ceramic element 1321 is arranged between the heating element 131 and the porous cotton rope element 1322. The porous ceramic element 1321 includes a first surface and a second surface relative to each other, the first surface faces the air outlet channel 15 as the atomizing surface of the atomizing core 13, the heating element 131 is arranged on the first surface, and a through groove 1323 is formed on the second surface, and the porous cotton rope element 1322 is arranged in the through groove 1323. It should be noted that in some embodiments, since the atomizing surface faces the air outlet channel, bubbles may be formed in the through groove 1323 of the porous ceramic element 1321 during the consumption of the atomizing matrix. The presence of bubbles will affect the lower liquid, resulting in insufficient liquid supply to the atomizing surface, which is prone to high temperature and burnt smell, affecting the user experience. In this embodiment, the porous cotton rope member 1322 is arranged in the through groove 1323. Since the aperture of the porous cotton rope member 1322 is much smaller than the aperture of the bubble, the formation and generation of bubbles can be avoided, the stability of the liquid is improved, local high temperature is avoided, and the user experience is improved. Furthermore, a convex rib 1324 is arranged on the bottom wall of the through groove 1323, which squeezes and fixes the porous cotton rope member 1322 while enhancing the strength of the porous ceramic member 1321.

[0079] In the width direction of the atomizer 1, first through holes 123 are provided on both opposite side walls of the base 12, so that the liquid guide 132 of the atomizer core 13 is exposed to the lower liquid channel 17. The atomizer 1 also includes a sealing component 19 disposed in the base 12, and the sealing component 19 is partially disposed between the atomizer core 13 and the base 12, so that the atomization surface of the atomizer core 13 is separated from the substrate to be atomized in the lower liquid channel 17, thereby achieving sealing of the atomizer core 13. In other words, the substrate to be atomized in the liquid storage chamber 14 enters the liquid guide 132 of the atomizer core 13 through the lower liquid channel 17, and the liquid guide 132 uses its capillary force to guide the substrate to be atomized to the atomization surface, thereby completing atomization.

[0080] A second groove 191 is disposed on the first surface of the sealing assembly 19 , and the atomizer core 13 is accommodated in the second groove 191 . Second through holes 1911 are disposed on opposite side walls of the second groove 191 at locations corresponding to the first through holes 123 , so as to expose the liquid guide member 132 of the atomizer core 13 , so that the liquid guide member 132 is exposed to the lower liquid channel 17 .

[0081] Furthermore, a depression 1912 is provided on the bottom wall of the second groove 191, and the depression 1912 extends along the width direction of the atomizer 1 and is connected to the second through hole 1911; a ventilation groove 1913 is provided on the side of the side wall of the second groove 191 close to the opening end. The cooperation between the depression 1912 and the ventilation groove 1913 realizes ventilation of the liquid in the liquid storage chamber 14, prevents negative pressure from being generated in the liquid storage chamber 14, and enables the substrate to be atomized in the liquid storage chamber 14 to smoothly enter the atomizer core 13, thereby preventing the atomizer core 13 from dry burning.

[0082] The outer surface of the sealing assembly 19 is provided with a first annular protrusion 192 and a second annular protrusion 193. The first annular protrusion 192 is provided on the side of the second through hole 1911 close to the air outlet channel 15, and the second annular protrusion 193 is provided on the side of the second through hole 1911 away from the air outlet channel 15; the first annular protrusion 192 and the second annular protrusion 193 are both in contact with the inner surface of the base 12. By providing the first annular protrusion 192, the atomizing surface of the atomizing core 13 is separated from the substrate to be atomized in the lower liquid channel 17, and the substrate to be atomized can only reach the heating element 131 through the liquid guide 132 of the atomizing core 13 to complete the atomization process. By providing the second annular protrusion 193, the substrate to be atomized is prevented from leaking from the bottom of the second groove 191, that is, the atomizer 1 is prevented from leaking.

[0083] A third groove 194 is provided on the second surface of the sealing assembly 19 opposite to the first surface. Figure 2 , a liquid absorbent cotton 195 is arranged in the third groove 194. By arranging the liquid absorbent cotton 195, even if the atomized matrix leaks out from the bottom of the second groove 191, it is absorbed by the liquid absorbent cotton 195, further preventing the atomizer 1 from leaking, thereby avoiding the influence of the leakage on the performance of the host 2, and improving the user experience.

[0084] Furthermore, a protrusion 1941 is provided on the bottom wall of the third groove 194 to form a micro groove. The micro groove cooperates with the liquid-absorbing cotton 195 to absorb and store the leaked liquid, thereby preventing the leaked liquid from entering the main unit 2.

[0085] See also Fig.15 , Fig.15 It is a schematic diagram of a partial cross section of the atomizer provided in the present application.

[0086] An air inlet hole 1951 is provided on the liquid absorbing cotton 195. In the thickness direction of the atomizer 1, two opposite side walls of the third groove 194 of the sealing assembly 19 are provided with connecting holes 1942, one end of the connecting hole 1942 is connected to the air inlet hole 1951, and the other end is connected to the first groove 1221 through the ventilation structure 121. In other words, the outside air reaches the atomization surface through the air inlet hole 1951, the connecting hole 1942, the ventilation structure 121, the first groove 1221, and the notch 1222.

[0087] It can be understood that the communication hole 1942 is arranged on the side wall of the third groove 194, and the air inlet 1951 is formed in the liquid absorbent cotton 195, and the liquid absorbent cotton 195 is arranged in the third groove 194; in order to ensure that the air inlet 1951 is connected with the communication hole 1942, there is a gap between the surface of the liquid absorbent cotton 195 close to the atomizer core 13 and the bottom wall of the third groove 194 to form a cavity 196, and the communication hole 1942 is connected with the air inlet 1951 through the cavity 196. The communication hole 1942 is at least partially exposed in the cavity 195, so that the communication hole 1942 is connected with the air inlet 1951.

[0088] In this embodiment, in the thickness direction of the atomizer 1, the two opposite side walls of the base 12 are provided with through holes (not shown) extending along the axis to form a ventilation structure 121. One end of the through hole is located on the side of the flange 122 away from the air outlet channel 15 and is connected to the flange 122, so that the through hole is connected to the first groove 1221. One end of the through hole is connected to the first groove 1221, and the other end is connected to the outside atmosphere through the connecting hole 195 and the air inlet 1941. In another embodiment, a fourth groove (not shown) extending along the axis is provided on the side wall of the base 12, and the fourth groove cooperates with the outer surface of the sealing assembly 19 to form a ventilation structure 121; one end of the fourth groove is located on the side of the flange 122 away from the air outlet channel 15 and is connected to the flange 122, so that the ventilation structure 121 is connected to the first groove 1221. The ventilation structure 121 can be designed as needed, so that the ventilation structure 121 can connect the outside atmosphere with the first groove 1221.

[0089] The atomizer of the present application includes a shell, an atomizer seat and an atomizer core; the shell forms an air outlet channel; the atomizer seat is provided with a ventilation structure and an air guide structure, and the ventilation structure connects the air guide structure with the outside atmosphere; the atomizer core is accommodated in the receiving cavity formed by the atomizer seat, and the atomizing surface of the atomizer core faces the air outlet channel; the air guide structure guides the airflow to flow to the atomizing surface in at least three directions and converges on the atomizing surface, and then enters the air outlet channel. By setting the atomizing surface of the atomizer core toward the air outlet channel, the path of the atomized aerosol of the atomizer core entering the air outlet channel is shortened to the maximum extent, and the amount of aerosol is increased; at the same time, the air guide structure guides the airflow to flow to the atomizing surface in at least three directions and converges on the atomizing surface, and then enters the air outlet channel, which reduces the generation of vortices on the atomizing surface, further reduces aerosol residue, and thus reduces the generation of condensate.
